What is angular-mocks?

The angular-mocks package provides mocking and testing utilities for AngularJS applications. It includes modules, services, and methods to facilitate unit testing and end-to-end testing of AngularJS code.

What are angular-mocks's main functionalities?

Mocking HTTP Requests

This feature allows you to mock HTTP requests in your AngularJS application. The code sample demonstrates how to use $httpBackend to intercept a GET request to '/api/data' and respond with a status code of 200 and a JSON object.

angular.module('myApp', ['ngMockE2E'])
  .run(function($httpBackend) {
    $httpBackend.whenGET('/api/data').respond(200, { key: 'value' });
  });

Injecting and Mocking Services

This feature allows you to inject and mock services in your unit tests. The code sample shows how to inject MyService and $httpBackend, set up an expectation for an HTTP GET request, and verify the response.

describe('MyService', function() {
  var MyService, $httpBackend;

  beforeEach(module('myApp'));
  beforeEach(inject(function(_MyService_, _$httpBackend_) {
    MyService = _MyService_;
    $httpBackend = _$httpBackend_;
  }));

  it('should fetch data', function() {
    $httpBackend.expectGET('/api/data').respond(200, { key: 'value' });
    MyService.getData().then(function(response) {
      expect(response.data.key).toBe('value');
    });
    $httpBackend.flush();
  });
});

Spying on Methods

This feature allows you to spy on methods to check if they have been called and with what arguments. The code sample demonstrates how to spy on the getData method of MyService and verify that it has been called when MyController is instantiated.

describe('MyController', function() {
  var $controller, $rootScope, MyService;

  beforeEach(module('myApp'));
  beforeEach(inject(function(_$controller_, _$rootScope_, _MyService_) {
    $controller = _$controller_;
    $rootScope = _$rootScope_;
    MyService = _MyService_;
  }));

  it('should call MyService.getData', function() {
    spyOn(MyService, 'getData').and.callThrough();
    var $scope = $rootScope.$new();
    $controller('MyController', { $scope: $scope });
    expect(MyService.getData).toHaveBeenCalled();
  });
});
